This patch adds a number of improvements to llvm-pdbdump.
1) Dumping of the entire global scope, and not only those
symbols that live in individual compilands.
2) Prepend class name to member functions and data
3) Improved display of bitfields.
4) Support for dumping more kinds of data symbols.

Port `DIExpression::Operand` over to `MDExpression::ExprOperand`. The
logic is needed directly in `MDExpression` to support printing in
assembly.

This commit makes the following changes:
- Stop issuing a warning when the triples' string representations do not match
exactly if the Triple objects generated from the strings compare equal.
- On Apple platforms, choose the triple that has the larger minimum version
number.

This is much more efficient. In particular, the query with the user
instruction has to insert a false for every missing instruction into the
set. This is just a cleanup a long the way to fixing the underlying
algorithm problems here.

When we try to estimate number of potentially removed instructions in
loop unroller, we analyze first N iterations and then scale the
computed number by TripCount/N. We should bail out early if N is 0.

Using this in combination with -ffunction-sections allows LLVM to output a .o
file with mulitple sections named .text. This saves space by avoiding long
unique names of the form .text.<C++ mangled name>.

Constant pool entries are uniqued by their contents regardless of their
type. This means that a pshufb can have a shuffle mask which isn't a
simple array of bytes.
The code path which attempts to decode the mask didn't check for
failure, causing PR22559.

I'd modify my migration tool to account for this, but this is the only
instance of a typedef'd pointer type to a gep I found in the whole test
suite, so it didn't seem worthwhile.

The PowerPC backend has long promoted some floating-point vector operations
(such as select) to integer vector operations. Unfortunately, this behavior was
broken by r216555. When using FP_EXTEND/FP_ROUND for promotions, we must check
that both the old and new types are floating-point types. Otherwise, we must
use BITCAST as we did prior to r216555 for everything.

The sub-arrays for compile units have for a long time been initialized
to distinct temporary nodes with the `DW_TAG_base_type` tag, with no
other operands. These invalid `DIBasicType`s are later replaced with
appropriate arrays.
This seems like a poor man's assertion that the arrays do eventually get
replaced. These days, temporaries in the graph will cause assertions
when writing bitcode or assembly, so this isn't necessary. Use
temporary empty tuples instead.
Note that the whole idea of using temporaries and then replacing them
later is wasteful here. We never actually want to merge compile units
by uniquing based on content. Compile units should use `getDistinct()`
instead of `get()`, and then their operands can be freely replaced later
on.

Frequently you only want to iterate over children of a specific
type (e.g. functions). Previously you would get back a generic
interface that allowed iteration over the base symbol type,
which you would have to dyn_cast<> each one of. With this patch,
we allow the user to specify the concrete type as a template
parameter, and it will return an iterator which returns instances
of the concrete type directly.

Summary:
Instances of the AssumptionCache are per function, so we can't re-use
the same AssumptionCache instance when recursing in the CallAnalyzer to
analyze a different function. Instead we have to pass the
AssumptionCacheTracker to the CallAnalyzer so it can get the right
AssumptionCache on demand.

0xFFFFFFFFFFFFFFFFLL doesn't fit in a long long so it should have
type 'unsigned long long'. MSVC thinks it's a (signed) __int64.

bfd creates the output file early, so calling exit(0) is not enough, the file needs to be explicitly deleted.
